CTL Pin Configuration for Notebook States
The CTL pins provide the user with mode flexibility. Specifically, within a notebook, states S0, S3, S4, and S5 are
important for controlling power consumption. For S0 the host controller is active, so either SDP or CDP should be
selected. The notebook is responsible for sourcing at least 500mA when SDP is selected and at least 1500 mA
when CDP is selected. Figure 44 illustrates the circuit connection forTPS2541 using one control signal (STATE).
When STATE = logic 0, auto detect is selected (S3/S4/S5, 1.5 A). When STATE = logic 1, CDP mode is selected
(S0, 1.5 A).
Figure 44. TPS2541 Application Using Single STATE Control Signal
Figure 45 illustrates the circuit connection for TPS2540/40A with STATE and ADAPTER control signals. If the
adapter is present (ADAPTER = logic 1), the TPS2540/40A supports auto detect operation when STATE = logic
0 (S3/S4/S5, 1.5 A) and CDP operation when STATE = logic 1 (S0, 1.5 A). If the adapter is not present
(ADAPTER = logic 0), the TPS2540/40A disables sleep charge when STATE = logic 0 (S3/S4/S5, power switch
off) and SDP operation when STATE = logic 1 (S0, 0.5 A).
